We live in a galaxy that is called the Milky Way. It's called a barred spiral galaxy, which means that it has a spiral shape with a bar of stars across its middle. The galaxy is rather huge—at least 100,000 ...

Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. ...

The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714. This galaxy has drifted too close to another nearby galaxy and the dramatic interaction has twisted its spiral ...

A detailed study of the motions of different stellar populations in the disk of the Andromeda galaxy has found striking differences from our own Milky Way, suggesting a more violent history of mergers with ...

A compelling new image from Gemini Observatory peers into the heart of a group of galaxies (VV166) traveling through space together. The variety of galactic forms range from a perfect spiral, to featureless ...

With the Atacama Large Millimeter/submillimeter Array (ALMA) observation, astronomers led by Shigehisa Takakuwa, Associate Research Fellow at the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA), ...

With the help of citizen scientists, a team of astronomers has found an important new example of a very rare type of galaxy that may yield valuable insight on how galaxies developed in the early Universe. ...

It is said to represent a "cosmic constant" found in the curvature of elephant tusks, the shape of a kudu's horn, the destructive beauty of Hurricane Katrina, and in the astronomical grandeur of how planets, ...

If you took a photograph of the Milky Way galaxy today from a distance, the photo would show a spiral galaxy with a bright, central bar (sometimes called a bulge) of dense star populations. The Sun—very ...

It's often said that the shape of a spiral galaxy follows the curve of a golden spiral. You can see this, for example, in the image above. While it's often implied that this curve matches exactly, that isn't ...

The image above shows a pair of colliding spiral galaxies known as Arp 274. What's interesting is not that they happen to be colliding, but that the two galaxies are spiraling in opposite directions. The ...

(Phys.org) —This new image from the NASA/ESA Hubble Space Telescope shows NGC 7793, a spiral galaxy in the constellation of Sculptor some 13 million light-years away from Earth. NGC 7793 is one of the brightest ...

The visible universe is vast. It is 93 billion light years across, and contains more than 100 billion galaxies. The average galaxy contains about 100 billion stars, and untold numbers of planets. Yet a century ...
